Sony has some great devices, but it looks like those in the two biggest smartphone markets in the world, China and the United States, won't be markets that Sony will be concentrating on going into the future.

The Japanese electronics giant will instead focus its business to markets where it is strong, which is Europe and Japan. Sony does not have any plans for "the world's two largest smartphone markets, China and the United States." Sony CEO, Kazuo Hirai, says: "Those two are the most important areas for us and we'll put substantial resources there. But not yet for the U.S. and China."

The US market is a hard one, and even harder for Sony as T-Mobile is the only major US carrier to offer consumers Sony smartphones. Moving to China, where "homegrown brands" like ZTE, Huawei and Xiaomi are making leaps and bounds, even in front of global superstar Apple and its iPhone.
